Question

Quizplus · Accepted Answer

A wave packet has the localized nature of a particle, the group velocity is identical to the speed of the particle, and the waves that compose the packet can show interference and diffraction. Therefore, all of the above reasons are valid justifications for representing a quantum particle with a wave packet.
